Given direct line segment PR below, find the coordinates of Q on PR such that the ratio of PQ to QR is 2:1 The coordinates on the graph are: P(-2,5) R(1,-7)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

9 x 8 divided by (5-3)=36
